《傅立叶分析导论》分为3部分：第1部分介绍傅立叶级数的基本理论及其在等周不等式和等分布中的应用；第2部分研究傅立叶变换及其在经典偏微分方程及Radom变换中的应用；第3部分研究有限阿贝尔群上的傅立叶分析。书中各章均有练习题及思考题。

Stein在国际上享有盛誉，现任美国普林斯顿大学数学系教授。

他是当代分析，特别是调和分析和分析领域领袖人物之一。古典调和分析最困难问题之一是推广到多维。他是多维欧氏调和分析的创造者之一，为此他发展了许多先进工具如奇异积分、Radon变换、极大函数等。他还发展了多个实变元的Hardy空间理论，推广了1971年F. John和L. Nirenberg的重要发现：即Hardy空间与BMO空间的对偶。在群上的调和分析方面也有贡献，例如同R.Kunze一起发现所谓Kunze-Stein现象。除此之外，他对多复变问题也做出了突出成绩。

除了研究工作之外，他的许多书成为影响学科发展的重要参考文献。为此，他荣获1984年美国数学会在论述方面的Steele奖。

由于他的成就，他在1974年被选为美国国家科学院院士，1982年被选为美国文理学院院士，1993年获得瑞士科学院颁发的Schock奖。1999年获得世界性Wolf数学奖。
